Noise is an omnipresent occupational hazard. So many workers, especially industry and construction workers all over the US, are exposed to excessive noise levels. Long-term exposure to these noise levels can cause hearing loss but can also affect human health in other ways. That’s why it’s so important to limit the exposure to excessive noise or, if that’s not possible, to use a hearing protection device (HPD). The market is flooded with all kinds of hearing protection earmuffs and earplugs, but which one should you choose? The most important characteristic you should be looking for when choosing a hearing protection device is the device’s noise reduction rating (NRR). In layman’s terms, noise reduction rating describes the ability of a certain HPD to attenuate noise. However, there’s
Finding the right speaker wire for your speaker system seems easy. You just have to find the wire that’s thick enough to fit the speaker terminals, right? Well, not exactly. There’s a little bit more to speaker wire than you may think. But don’t worry - it’s not too complicated. We are here today to tell you everything you need to know about speaker wire. We will discuss the gauges, wire materials, important electrical characteristics, installation process, and tell you about some tricks and marketing gimmicks the manufacturers use to sell their wire. Let’s go! What is Speaker Wire? Speaker wire is a cable used to connect amplifiers to speakers. This cable sends amplified audio to the speakers. It has a core, which is usually made of copper and can be either stranded or solid and a
Whenever looking for waterproof or water-resistant equipment, whether it's audio equipment (headphones, speakers) or any kind of electrical/electronic equipment, the most important thing to look for and the thing that can actually tell you the level of water resistance is the IPX rating. In our previous articles, we dealt with IPX ratings in general as well as IPX4 (splash-proof) and IPX7 (waterproof). Today we’re going to discuss the meaning and importance of an IPX8 waterproof rating. IP/IPX Ratings – The Basics IP stands for Ingress Protection (also referred to as International Protection). It is an internationally standardized rating that describes the level of protection against the ingress of solid particles, dust, and water. An IP rating has a general form that you can see
If you are looking to buy an outdoor speaker or sports headphones/earbuds and you did your research, you have probably seen some IPX rating in the specification list or on the box of the device you want to buy. Most of today’s outdoor speakers and sports headphones/earbuds have at least IPX4 rating and some even have IPX7 or IP67 ratings. In case you are not sure what those ratings actually mean, this short article will help you understand the purpose and meaning of each IP/IPX rating. What is IPX Rating and Why is it Important? IP stands for International Protection or, in some cases, Ingress Protection. IP (or IPX) rating is the marking that describes the level of protection (provided by the enclosure of the device) against dust, water, and ingress of other particles or fluids. You

If you've been trying recently to get a deeper understanding of power amplifiers, you have probably come across terms AC amplifier and DC amplifier. What was your first thought? Was it Alternating Current and Direct Current? Well, terms AC and DC in amplifiers don't exactly refer to current. These terms refer to the coupling method between different stages of amplification. Our article is designed to help you understand the working principles of each of these two amplifier types, and explain the differences between AC and DC amplifiers. What is The Meaning of AC and DC in AC/DC Amplifiers? AC in AC amplifiers tells us that different stages of amplification are coupled with a capacitor or a transformer. These capacitors/transformers are, therefore, known as coupling capacitors/tr...
